How to plug in your Obi300 device for your T.38 Fax line service?

Once you have received your package in the mail, open it up!

The three things you need from your box are the Obi300 device, the power supply and the ethernet cable included.

Connect the Obi300 to your router or switch with the included ethernet cable. If you already have a network cable setup that is properly connected to your router or switch, go ahead and use that one instead.

You must plug the ethernet cable into the blue coloured “INTERNET” port of the Obihai and the other end in one of the LAN ports in your router or switch.

Plug in the power supply of the Obihai 300, the power light will start flashing for a few minutes, and then you should have a total of three green LEDs lit up, including the handset icon LED on the right hand side of the box.

Plug in your fax machine RJ-11 cable into the “PHONE 1” jack of the Obihai 300, and you can now send and receive faxes with your machine.
